//A buffer is a linear, finite sequence of elements of a specific primitive type. Aside from its content,
//the essential properties of a buffer are its capacity, limit, and position:
//
//A buffer's capacity is the number of elements it contains. The capacity of a buffer is never negative and never changes.
//
//A buffer's limit is the index of the first element that should not be read or written.
//A buffer's limit is never negative and is never greater than its capacity.
//
//A buffer's position is the index of the next element to be read or written.
//A buffer's position is never negative and is never greater than its limit.
